 * About: Introduction
 * 
 * jqPlot requires jQuery (1.4+ required for certain features). jQuery 1.4.2 is included in the distribution.  
 * To use jqPlot include jQuery, the jqPlot jQuery plugin, the jqPlot css file and optionally 
 * the excanvas script for IE support in your web page:
 * 
 * > <!--[if lt IE 9]><script language="javascript" type="text/javascript" src="excanvas.js"></script><![endif]-->
 * > <script language="javascript" type="text/javascript" src="jquery-1.4.4.min.js"></script>
 * > <script language="javascript" type="text/javascript" src="jquery.jqplot.min.js"></script>
 * > <link rel="stylesheet" type="text/css" href="jquery.jqplot.css" />
 * 
 * jqPlot can be customized by overriding the defaults of any of the objects which make
 * up the plot. The general usage of jqplot is:
 * 
 * > chart = $.jqplot('targetElemId', [dataArray,...], {optionsObject});
 * 
 * The options available to jqplot are detailed in <jqPlot Options> in the jqPlotOptions.txt file.
 * 
 * An actual call to $.jqplot() may look like the 
 * examples below:
 * 
 * > chart = $.jqplot('chartdiv',  [[[1, 2],[3,5.12],[5,13.1],[7,33.6],[9,85.9],[11,219.9]]]);
 * 
 * or
 * 
 * > dataArray = [34,12,43,55,77];
 * > chart = $.jqplot('targetElemId', [dataArray, ...], {title:'My Plot', axes:{yaxis:{min:20, max:100}}});
 *

     * Namespace: $.jqplot
     * jQuery function called by the user to create a plot.
     *  
     * Parameters:
     * target - ID of target element to render the plot into.
     * data - an array of data series.
     * options - user defined options object.  See the individual classes for available options.
     * 
     * Properties:
     * config - object to hold configuration information for jqPlot plot object.
     * 
     * attributes:
     * enablePlugins - False to disable plugins by default.  Plugins must then be explicitly

     *   This property sets the "show" property of certain plugins to true or false.
     *   Only plugins that can be immediately active upon loading are affected.  This includes
     *   non-renderer plugins like cursor, dragable, highlighter, and trendline.
     * defaultHeight - Default height for plots where no css height specification exists.  This
     *   is a jqplot wide default.

/**
     * Class: $.jqplot.ThemeEngine
     * Theme Engine provides a programatic way to change some of the  more
     * common jqplot styling options such as fonts, colors and grid options.
     * A theme engine instance is created with each plot.  The theme engine
     * manages a collection of themes which can be modified, added to, or 
     * applied to the plot.
     * 
     * The themeEngine class is not instantiated directly.
     * When a plot is initialized, the current plot options are scanned
     * an a default theme named "Default" is created.  This theme is
     * used as the basis for other themes added to the theme engine and
     * is always available.
     * 
     * A theme is a simple javascript object with styling parameters for
     * various entities of the plot.  A theme has the form:
     * 
     * 
     * > {
     * >     _name:f "Default",

     * override any styles on the individual axes.

/**
     * JavaScript printf/sprintf functions.
     * 
     * This code has been adapted from the publicly available sprintf methods
     * by Ash Searle. His original header follows:
     *
     *     This code is unrestricted: you are free to use it however you like.
     *     
     *     The functions should work as expected, performing left or right alignment,
     *     truncating strings, outputting numbers with a required precision etc.
     *
     *     For complex cases, these functions follow the Perl implementations of
     *     (s)printf, allowing arguments to be passed out-of-order, and to set the
     *     precision or length of the output based on arguments instead of fixed
     *     numbers.
     *
     *     See http://perldoc.perl.org/functions/sprintf.html for more information.
     *
     *     Implemented:
     *     - zero and space-padding
     *     - right and left-alignment,
     *     - base X prefix (binary, octal and hex)
     *     - positive number prefix
     *     - (minimum) width
     *     - precision / truncation / maximum width
     *     - out of order arguments
     *
     *     Not implemented (yet):
     *     - vector flag
     *     - size (bytes, words, long-words etc.)
     *     
     *     Will not implement:
     *     - %n or %p (no pass-by-reference in JavaScript)

      * 
      * Added %p %P specifier
      * Acts like %g or %G but will not add more significant digits to the output than present in the input.
      * Example:

      * Format: '%.3g', Input: 0.012, Output: 0.0120

      * Format: '%.4g', Input: 12.0, Output: 12.00
      * Format: '%.4p', Input: 4.321e-5, Output: 4.321e-5
      * Format: '%.4g', Input: 4.321e-5, Output: 4.3210e-5
      * 
      * Example:
